I was asked to write a program that finds the solutions, if any, to a given quadratic equation. My code is below. I have two issues: First When i input for example, a=3, b=4, c=5 the result prints" The roots are -nan and -nan" Secondly, I am to ensure that division by 0 is not permitted and the discriminant b^2-4ac cannot be negative. I am having a hard time with this bit. Could you help me solve this part?

Is there any code handy?
